{"product_id":"zipp-303-xplr-s-carbon-gravel-rear-wheel-b1","title":"303 XPLR S Carbon Gravel Rear Wheel B1","description":"\u003cp\u003eThe Zipp 303 XPLR S rear wheel delivers a big gravel upgrade without the big price tag, pairing a mega-wide, fast-rolling rim with the drive-side stiffness to put power down on rough, loose ground. It applies Zipp's Total System Efficiency thinking to the specific demands of gravel riding.\u003c\/p\u003e\n\u003cp\u003eThe ultra-wide 32mm internal rim boosts tyre air volume so you can run pressures under 30psi without squirm — cutting the surface vibrations that slow you down, while adding grip and climbing traction. The wide, 54mm-deep profile blends smoothly into approved gravel tyres for real aero efficiency, and despite being built big it stays light to keep you fresh on long days.\u003c\/p\u003e\n\u003cp\u003eIt's a hookless, tubeless carbon rim laced to Zipp's 176 rear hub with 36 points of engagement, available with a SRAM\/Shimano HG or SRAM XDR freehub. Please note the 303 XPLR is compatible only with Zipp-approved tyres. Available in Dark Grey or White, with Zipp's lifetime warranty.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMega-wide 32mm internal rim — run gravel tyres below 30psi without squirm\u003c\/li\u003e\n\u003cli\u003e54mm deep, wide profile integrates with approved tyres for aero efficiency on gravel\u003c\/li\u003e\n\u003cli\u003eHookless carbon, tubeless rim built light and robust for long days\u003c\/li\u003e\n\u003cli\u003eZipp 176 hub with 36 points of engagement\u003c\/li\u003e\n\u003cli\u003e700c, disc brake (Center Lock), 12 × 142mm thru-axle\u003c\/li\u003e\n\u003cli\u003eChoice of SRAM\/Shimano HG or SRAM XDR freehub\u003c\/li\u003e\n\u003cli\u003eCompatible with Zipp-approved tyres only (40–61c); lifetime warranty; Dark Grey or White\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eWheel: Rear\u003c\/li\u003e\n\u003cli\u003eDiscipline: Gravel\u003c\/li\u003e\n\u003cli\u003eRim depth: 54mm\u003c\/li\u003e\n\u003cli\u003eRim construction: Carbon, hookless\u003c\/li\u003e\n\u003cli\u003eInternal rim width: 32mm\u003c\/li\u003e\n\u003cli\u003eMax outside width: 40mm\u003c\/li\u003e\n\u003cli\u003eTyre compatibility: Approved tubeless (TLR) tyres 40–61c, tube or sealant\u003c\/li\u003e\n\u003cli\u003eBrake: Disc, Center Lock\u003c\/li\u003e\n\u003cli\u003eAxle: 12 × 142mm\u003c\/li\u003e\n\u003cli\u003eFreehub: SRAM\/Shimano HG or SRAM XDR\u003c\/li\u003e\n\u003cli\u003eHub: Zipp 176, 36 points of engagement\u003c\/li\u003e\n\u003cli\u003eBearings: Stainless steel cartridge\u003c\/li\u003e\n\u003cli\u003eMax tyre pressure: 50psi \/ 3.45 bar\u003c\/li\u003e\n\u003cli\u003eMax system weight: 135kg \/ 298lbs\u003c\/li\u003e\n\u003cli\u003eWarranty: Lifetime\u003c\/li\u003e\n\u003cli\u003eColours: Dark Grey, White\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Zipp","offers":[{"title":"Dark Grey \/ 12 x 142mm HG","offer_id":58184658125174,"sku":"ZPWH8805000","price":600.0,"currency_code":"GBP","in_stock":true},{"title":"White \/ 12 x 142mm HG","offer_id":58184658157942,"sku":"ZPWH8805001","price":600.0,"currency_code":"GBP","in_stock":true},{"title":"Dark Grey \/ 12 x 142mm XDR","offer_id":58184658190710,"sku":"ZPWH8805002","price":600.0,"currency_code":"GBP","in_stock":true},{"title":"White \/ 12 x 142mm XDR","offer_id":58184658223478,"sku":"ZPWH8805003","price":600.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0568\/3065\/6691\/files\/303-xplr-s-carbon-gravel-rear-wheel-b1-dark-grey-12-x-142mm-hg-1246720737.jpg?v=1782895255","url":"https:\/\/www.biketart.com\/products\/zipp-303-xplr-s-carbon-gravel-rear-wheel-b1","provider":"Biketart","version":"1.0","type":"link"}
